The abbreviations for a tetragram, a nanosecond and a kiloliter are as follows:
Tg ,ns and kl.
Nanosecond is *10-9.
One teragram is ten raised to the power of 9 and one kiloliter is equivalent to one thousand liters.

Answer:
The correct answer is c. 3/16.
Explanation:
In the given question two traits being studied, the traits are flower color and seed shape.
This is a typical Mendel’s dihybrid cross. According to the question purple colour (P) and round seed (R) are dominant traits.
When heterozygous purple-flowered (Pp), round-seeded (Rr) individuals are crossed, four different types of plants are produced phenotypically in the ratio 9:3:3:1.Out of 16 offspring, 9 are purple flowered, round seeded pea plants, 3 pea plants are white-flower with round seed, 3 are purple- flower with wrinkled seed and 1 pea plant is white-flowered with wrinkled seed pea plant is produced.
Multiply by the power of the eyepiece, usually 10x.
